| Outline of Final Research Achievements |
This study, we examined the effect of dopamine (DA) and noradrenaline (NA) on the GABAergic transmission of layer V pyramidal cells in the medial prefrontal cortex (prelimbic cortex and anterior cingulate cortex; ACC) and Purkinje cells in the cerebellum using ADHD model and control rats. We found that the application of DA caused the enhancement of IPSC amplitude which is larger in control than in ADHD model rats recorded in ACC region. Pharmacological studies revealed that the enhancement is mediated by the activation of D1-like receptors. On the other hand, there were no differences the effect of NA application on IPSC amplitude which recorded in pyramidal and Purkinje cells.
